Hi Bob,
Thanks for contacting Syncfusion Forums.
QUERY1: the ServerRowDeselected event never seems to fire
From your query we understand that, the OnServerRowDeselected event doesn’t fires. When you use both OnServerRowSelected, OnServerRowDeselected event , select a row, the OnServerRowSelected event will be triggered. When you select another row, the OnServerRowDeselected event will not be triggered for the deselected row, instead the OnServerRowSelected event will be triggered for newly selected row. This is the behavior of grid.
QUERY2: when I click the header to sort it deselects the current row (so none are selected) but as it doesn’t seem to raise an event I can’t reset my internal ‘SelectedIndex’ flag to -1
When you select and sort the grid, the grid rows get sorted, which means the row you have selected could have been in different page. After sorting, you no longer do any operation with that selected row, since it may not be in the current page. You have mentioned that you need to set internal flag. Please do clarify your requirement and scenario, so that we could help you to achieve it.
QUERY3: I can’t find how to check what the current grid selected row or index is programmatically in my c# code behind
You can set a button, bind OnClick event to it, and get the current grid selected row from GridId.SelectedRowIndex in code behind.
Please refer the below code snippet,
|
<ej:Button ID="btn_Click" runat="server" OnClick="btn_Click_Click" Size="Normal" Text="Click to Select"></ej:Button>
<ej:Grid ID="OrdersGrid" runat="server"
-----------
<Columns>
----
</Columns>
</ej:Grid>
In code behind
protected void btn_Click_Click(object Sender, ButtonEventArgs e)
{
if(OrdersGrid.SelectedRowIndex != -1) {
// GridId. SelectedRowIndex will give selected rownindex
--------
}
}
|
Please refer the below screenshot,
QUERY4: How do I programmatically select a row on one of the grid pages and ensure its visible
For selecting the last added row, you can call SelectRows method and pass the index of newly added record to that method in actioncomplete event with args.requestType as “save” and args.action as “add” to select the newly added row.
Please refer the below code snippet,
|
<script>
function complete(args) {
if (args.requestType == "save" && args.action == "add") {
this.selectRows(index); // index= index of newly added row
}
}
</script>
